Other causes of corneal ulcers include: Abrasions or burns to the cornea caused by injury to the eye. Scratches, scrapes and cuts from fingernails, paper cuts, makeup brushes and tree branches can become infected by bacteria and lead to corneal ulcers. Burns caused by caustic chemicals found in the workplace and at home can cause corneal ulcers.
Ulcers also can be associated with other diseases, particularly connective tissue diseases such as lupus or BehÃ§et's syndrome, which cause symptoms on the eyes and genitals as well as the mouth. There can be one or many ulcers at the same time, and they are recurrent, which means they keep returning.
